Hi team,

My customer would like to know if we have the similar function with automotive open loop current transducer - HC5FW 900-S/SP1 ?

Please refer to attachment. Thanks

Best Regards,

Alex,

We have analog front ends like the DRV401. We also have the TMSC1100 which is an integrated magnetic current sensing device. The issue is we normally only have IC and not a full product module sensor like you have attached. We also have hall sensors that could be used to get magnetic information from a current to calculate the current. The challenge there is they would need to design the magnetic core as well.

Hi Javier,

Thanks for your information. Do we have the high AC current sensor about +- 900A for Automotive?

BR,

Alex

Alex,

We do not have a stand alone current sensor that can handle that. You can use the DRV401/DRV421 but the magnetic need to be designed. The DRV425 can be used on a bus bar as seen here, and you can order an example of 100A here. That is all we have at this time. All these solutions require design efforts.
